夏季天气炎热,气温常在36℃左右.高温季节如仍按照常规方法防治鱼病.不仅效果不明显,还易引起大批死亡。因此,高温季节防治鱼病应注意以下10个方面:①鱼塘水深平均不到80厘米,水温在30℃以上时,鱼药不可全池泼洒,否则会引起死鱼。因为温度每上升1℃,药物反应速度加快1倍;每上升10℃.其毒性会增加2—3倍.②漂白粉、硫酸铜、敌百虫均不能与生石灰同时施用.以免疗效减弱,因敌百虫与碱发生反
The hot summer weather, the temperature is often around 36 ℃ .High temperature season is still in accordance with the conventional method of prevention and treatment of fish diseases. Not only the effect is not obvious, but also easily lead to a large number of deaths. Therefore, hot season prevention and treatment of fish disease should pay attention to the following 10 aspects: ① average depth of less than 80 cm fish ponds, the water temperature above 30 ℃, the fish can not be completely pond spilled, otherwise it will cause dead fish. Because the temperature rises 1 ℃ every time, the drug reaction speed accelerates 1 times; Every rise 10 ℃. Its toxicity will increase 2-3 times. ② bleaching powder, the copper sulfate, the trichlorfon both can not simultaneously with quicklime, lest curative effect weakened, because enemy Insects and alkalis occur counter
